Neurology:外部三叉神经刺激对耐药性癫痫或有效

2013-03-09 高晓方 医学论坛网

  美国学者的一项研究表明,在耐药性癫痫患者中外部三叉神经刺激(eTNS)安全并可能具有治疗效果。论文发表于《神经病学》[Neurology 2013; 80(9):786]。   此项双盲随机对照研究共纳入50例耐药性癫痫患者,并随机给予为期18周的eTNS 120Hz(治疗组)或eTNS 2Hz(对照组)治疗。基线时受试者每月出现2次及以上部分性癫痫发

  美国学者的一项研究表明,在耐药性癫痫患者中外部三叉神经刺激(eTNS)安全并可能具有治疗效果。论文发表于《神经病学》[Neurology 2013; 80(9):786]。

  此项双盲随机对照研究共纳入50例耐药性癫痫患者,并随机给予为期18周的eTNS 120Hz(治疗组)或eTNS 2Hz(对照组)治疗。基线时受试者每月出现2次及以上部分性癫痫发作。在急性治疗期6、12和18周对癫痫发作情况进行评估。

  结果显示,入组时受试者均伴有高度耐药性癫痫;治疗组和对照组癫痫发作平均分别为8.7次和4.8次/月。受试者入组前平均出现3.35种抗癫痫药物治疗失败;治疗组和对照组癫痫持续时间分别为21.5和23.7年。eTNS耐受性良好;副作用包括焦虑(4%)、头痛(4%)和皮肤刺激(14%)。以癫痫发作频率降低50%以上定义有效,则18周治疗期间治疗组和对照组的有效者比率分别为30.2%和21.1%(p = 0.31)。治疗组的有效者比率在试验期间出现显著改善,由6周时17.8%升高至18周时40.5%(P=0.01)。治疗组受试者较对照组更有可能出现有效反应(比值比1.73)。eTNS与发作频率降低(p = 0.04)以及Beck抑郁量表中情绪改善(p = 0.02)具有相关性。
